Avalanche Summary
Observations from alpine terrain in this forecast region have been limited. We suspect that natural avalanches have been occurring at high elevations where precipitation has been falling as snow.
Snowpack Summary
In high alpine terrain recent precipitation may have fallen as snow and formed storm and wind slabs. At treeline the majority of recent precipitation has fallen as rain, with fluctuating freezing levels a mix of heavy snow and crusts could be found. Below treeline the snowpack is saturated and disappearing.

Terrain and Travel Advice
- Choose conservative terrain and watch for clues of instability.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
Avalanche Problems
Loose Wet
Wet loose avalanches will be possible in steep terrain where the snow surface is wet. They will be largest at treeline and alpine, where precipitation initially fell as snow and now is being soaked by rain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2
